My dog ate Plum - what should I do?
Prunus domestica
Potentially toxic
Contact your veterinarian or an animal poison-control resource now, especially if any amount was chewed or swallowed.
Verified against ASPCA/provenance audit 2026-05-06 on May 6, 2026.
Signs to watch for
Vomiting, diarrhea, abdominal pain, and potential respiratory distress.
Escalation note
The stems, leaves, and seeds are toxic due to the presence of cyanide precursors. If ingestion occurs, contact your veterinarian or an animal poison control center right away.
What to watch for
Vomiting, diarrhea, and abdominal pain may come first; the cyanide signature follows — panting, rapid or labored breathing, brick-red gums, dilated pupils, weakness, and shock. Whole-pit ingestion can also cause GI obstruction.
Time window
Cyanide onset is minutes to about an hour after kernel ingestion; signs can progress within hours. Uncomplicated GI upset typically resolves in 24-48 hours.
When to call the vet
Call immediately if a pit was crushed or chewed open, or if leaves or wilting material were eaten. Any labored breathing, gum-color change, or collapse is a same-minute emergency. Whole-pit swallows warrant a same-day call for obstruction risk.
What this means for your dog
Dogs are more likely than cats to crack a plum pit because of their stronger bite, which makes them the higher-risk pet for cyanide poisoning from this plant. The cyanogenic compounds live in the inner kernel, leaves, stems, and especially wilting material — not the ripe fruit's flesh.
